    Does anyone know if this is a viable display for use with the Arduino on the Udoo X86?

    Arduino UNO is 5v, and there is no mention of whether that display has been designed to work also with 3.3v. With so low price, it might not be.

    Quick Search (no guarantees): it is 3.3V compatible as the same LCD controller ili9488 it works on an Arduino Due https://wn.com/arduino_due_3.95_ili9488_8bit_480x320

    You have to search if the Arduino Library that is used (or you want to use) to control the LCD is Arduino 101 compatible. That likely will be your hardest struggle you will face to get this LCD working..

    First, I apologize for the gigantic post of eBay stuff. I tried to edit-out the irrelevant parts, but couldn't seem to get the forum editor to cooperate.

    Thank you for providing constructive information about use of this device with the Udoo X86.

    As I have no familiarity whatsoever with Arduino hardware, I am unable to provide much useful insight into the use of this display with the X86.

    The Udoo X86 User Manual indicates: "The UDOO X86 contains an embedded Intel Arduino 101".
    Under the Arduino Tech Specs tab on this page it mentions "Operating Voltage 3.3V (5V tolerant I/O)" but I am unable to confirm that spec. makes the display compatible with the Udoo X86.

    The Ilitek ILI9488 Specification datasheet, on page 323, indicates the "17.2. DC Characteristics for Panel Driving"

    Item Symbol Condition Min. Typ. Max. Unit Note
    Input and Output
    Logic High Level Input Voltage VIH - 0.7*IOVCC - IOVCC V
    Logic Low Level Input Voltage VIL - DGND - 0.3*IOVCC V
    So, I believe there is sufficient hardware information available to work out the compatibility issue.

    A search for Arduino software support turns up scads of stuff:

    Perhaps someone with more familiarity with the Arduino can provide more specific insight on how this inexpensive, touch-enabled, color, 3.5" display might be integrated into a Linux-based (and/or Windows-based) system to provide an interactive console display, auxiliary display for SSH, or other system i/o.

    The display pcb hosts logic level converters (U2, U3) which make the connector pins 5v tolerant, although I can't be 100% sure I would expect the display I/O pins (LCD_xxx) to 3.3v compatible and not present a problem interfacing to the 101. The display presents a simple 8 bit parallel interface with another 5 lines for control so therefore most of the GPIO lines on the 101 will be occupied. As already mentioned the leg work is reworking the Arduino GFX libraries to talk to display, if you know what your doing its possible to do this (have done it for other displays). The display is advertised with touch however it won't be possible to use touch + lcd at the same time using the Arduino 101 (without additional circuitry).

    In my opinion its not practical to the interface the display to the Arduino 101 and expect it be controlled from Linux/Windows, the frame refresh rate would be a bottleneck. If you want to use a small display from Linux/Windows best option is get one with a hdmi interface.

    BTW the Curie 101 was intended for wearable applications hence the inclusion of BLE + IMU + low power, so your use case isn't the best fit. Furthermore having it soldered on to a motherboard isn't ideal.
